He it known that I. ammm M. ri-11.011, a citixen of the United States, residingatt `olumbus` in the county of Franklin and State of ()hio, have in vented or discoverial certain new and useful lmpriivements in (las-Burners, of which improvements the following is a specilication.

'l`he inveution described herein relates to certain improvements in the class or kind of burners forming the subject-matter of an application liled byme May-l, llotand numbered serially IHLI'TB, and has for its object a construction and combination of parts wherehy a very accurate regulation and adjustment of the tlow of gas may be obtained. The invention is hereinafter more fully described and claimed.

ln the aceompanying drawings, forming a part of this specilication, Figure l is a sectional elevation of my improved burner. Fig. 2 is an end view of the regulating-sleeve. Fig. P, is a sectional view of a moditication in the construction of the adjustable member.

ln the practice ofmy invention I provide an annular Chamber 1, prefcrably formed in an annular block This chamber is connected by one or more pipes 3 with a gas-supply, and a slot -.t, preferably continuous, is formed through the inner walls of the annular chainber. lt will be understood that the continuity will not be materially interrupted if transverse braces are arranged at intervals. The walls of the slot are given an inclination toward the axis of the annular' block, so as to direct the gas toward the discharge end of the burner, which is formed by a tubular tip 5, secured to the block in any suitable manner. Vln order to regulate the tlow of gas, an internal sleeve ti is arranged to move along the annular block and across the slot lt is preferred that the block should be internally threaded for etfecting the longitudinal adjustment of the sleeve. The inner end of the sleeve is notched, the notches varying in length, so that as the end of the sleeve is moved across the continuous slot in the annular block the tlow of gas will be substantially proportional to the number of notches in the sleeve registering with the continnous slot.

Specification of Letters Patent.

Patented Sept. 5, 1905.

VSerial No. 266,458.

B the adjustment of the sleeve a l'low of gas equal to the full capacity of the slot can be had, or such tlow can be reduced to a minimum or entirely stopped. ltis prel'erred that the walls of the notches should be at an angle to radial planes, as shown in Fig. 2, so that a rotary movement or swirl may he given to the gas, thereby insuring a thorough mixture of the gas with the air llowing in through the sleeve. more accurate adiustment of the llow of gas can he ohtained by making the notches V-shaped, as shown in Fie'. 3. In the construction shown a reduction ol' llow can be had without shifting any of the notches out of register with the continuous slot. ln order that the gas may at all times llow into the sleeve at a plurality of points, it is preferrial to arrange the, notches in series and employ a plurality of series. lCaeh series contains a plurality of notches u e, &c., varying in length from the lougest to the shortcst notch cmployed. It will be understood that the sleeve can be shifted so that only notches u of each series are in register with the slot, or so shifted that any desired number of notches of the several series will so register.

I claim heroin as my invention" 1. A gas-burner having in combination a chambered annular block, the inner wall of said chaniber being slotted and asleeve movable in said block and provided with notches varying in length.

2. A gas-burner having in combination a chambered annular block, the inner wall of said chamber being slotted and a sleeve movable in said block and provided with notches varying in length and having their walls at an angle to radial planes.

3. A gas-burner having in combination a chambered annular block, the inner wall of the Chamber being slot-ted and a sleeve movahle in said block and provided with V-shaped notches.

ln testimony whereof l have hereunto set my hand.
